Abstract

A three-cell 1.3 GHz, Normal Conducting (NC) buncher is designed for a possible future upgrade of the European X-ray Free Electron Laser (Eu-XFEL) to operate in a continuous-wave (CW)/ long pulse (LP) mode. The RF geometry of the buncher is optimized for high shunt impedance, large mode separation as well as multipacting free in the operation range. The nominal buncher voltage is 400 kV with an RF power dissipation of 14 kW, and its shunt impedance is ∼50% higher than existing CW bunchers. The RF power coupler cell is optimized for field symmetry to minimize coupler kick effect on beam dynamics. The thermal load due to RF power dissipation is analyzed using Multiphysics simulations in CSTMWS and a cooling scheme is designed.
